A California representative has apologized after she was caught on camera imitating a Native American “war cry.”

Rep. Loretta Sanchez (D-Calif.), who is running for U.S. Senate, made the “war cry” over the weekend while talking to Indian Americans.

The LA Times reported:

Sanchez, the daughter of Mexican immigrants, made the controversial gesture Saturday while joking with a group of Indian Americans about confusing an Indian American with a Native American. Video of the gaffe on Twitter and YouTube showed Sanchez tapping her hand to her mouth in an imitation of a war cry.

Sanchez’s stumble was the talk of the convention Saturday night. Her apology overshadowed the rest of what was supposed to be her first major speech framing the Senate campaign that she launched on Thursday.

The Senate candidate addressed the gesture Sunday at the state Democratic Party convention.

“In this crazy and exciting rush of meetings yesterday, I said something offensive, and for that, I sincerely apologize,” she said.

Sanchez is running to replace Sen. Barbara Boxer.
